This is a thought that I have been chewed on it for a time. It implies that given all the different bike types and accessories, they tell about their personality and interests owners somehow. Indeed, when you periodically meet bikers from time to time, for instance in the Critical Mass, you could not remember the name of each and every cyclist if it is a numerous group. But you recognize them by their bicycles if you have previously seen their possessors, even if you have not meet them for a long time giving they still maintain the same bike. Personality is shown through bike kinds (mountain bike – a person who enjoys riding mountains, hybrid bike – possibly somebody who does bike-tourism, road bike, etc.) and accessories (bicycle basket – there is or has been a child, saddlebags – a bike-tourist, rear-view mirror – somebody who usually pedals on car lines…).
